ArcEngine中的Statistics类的例子
||
用对于这个类的属性statistics_fields的类型，help里面说的不清楚，写程序时不知道如何下手。用baidu,google搜了半天，居然全世界只能找到这样一个例子，赶紧转帖收藏，免得不见了。

| Message | Hi, I am trying to use the Geoprocessor -> Analysis Tools -> Statistics Tool from C# and find that the documentation is not helping me. What are the parameters for the Statistics tool ? Does anyone have any samples ? any help would be appreciated. thanks, |
ITable inTbl = clsGDBWorkSpaceManager.openTable("Table1", pws);
ITable outTbl = clsGDBWorkSpaceManager.openTable("Table2", pws);
IField f1 = inTbl.Fields.get_Field(inTbl.FindField("F1"));
IField f2 = inTbl.Fields.get_Field(inTbl.FindField("F2"));
Geoprocessor GP = new Geoprocessor();
ESRI.ArcGIS.AnalysisTools.Statistics s = new Statistics();
s.in_table = inTbl;
s.out_table = outTbl;
s.case_field = f1;
s.statistics_fields = "Sum.F2";
GP.Execute(s, null);

| Message | I agree that the Geoprocessing documentation leaves something to be desired. Usually, I use the Toolbox to create the type of process I intend to code and get the parameters from the dialog box. In the case of Statistics, this is the line that one test executes: Executing (Statistics_1): Statistics D:DatatestingBujaExport_Output.dbf D:DatatestingBujaExport_Output_Statistics.dbf "HAUL SUM" # I was getting the Sum of the field Haul, so in your case, try s.statistics_fields = "F2 Sum"; |

| Message | Thanks a lot Ken. With your suggestion i was able to get it running. IWorkspace pws = clsGDBWorkSpaceManager.openGDBWorkSpace(clsGDBWorkSpaceManager.GDBType.FileGDB, pth, fileNm, 0); ITable inTbl = clsGDBWorkSpaceManager.openTable("Table1", pws); //ITable outTbl = clsGDBWorkSpaceManager.openTable("Table2", pws); IField f1 = inTbl.Fields.get_Field(inTbl.FindField("F1")); IField f2 = inTbl.Fields.get_Field(inTbl.FindField("F2")); Geoprocessor GP = new Geoprocessor(); ESRI.ArcGIS.AnalysisTools.Statistics s = new Statistics(); s.in_table = @"D:FDOTworkQCEW_DataWorkAppsDataq1.gdbTable1"; s.out_table = @"D:FDOTworkQCEW_DataWorkAppsDataq1.gdbTable1_Statistics"; s.case_field = "F1"; s.statistics_fields = "F2 SUM;F3 SUM"; GP.Execute(s, null); No where in their(ESRI) poor quality documentation, did they mention the input param "object inoutTableName" is actually a string or the field names should be semi colon separated. How are we supposed to know all these ? anyway thanks for taking the time to help me out. capton. |
