GcMask

请问WinForm.net的画面里，GcMask控件如何设定只能输入大写英文和数字

GcMask 有一个Fields属性，可以加相应的FormatPattern.

GrapeCity.Win.Editors.Fields.MaskPatternField maskPatternField1 = new GrapeCity.Win.Editors.Fields.MaskPatternField();
maskPatternField1.Pattern = "\\D|\\A";
this.gcMask1.Fields.AddRange(new GrapeCity.Win.Editors.Fields.MaskField[] {maskPatternField1});
